“Not only did we cover many of attacks the White House released, we covered them heavily,” he said Monday night on “Anderson Cooper 360.” “I know because I was there on the ground reporting a number of them. ‘360’ was in Ottawa, Canada, October of 2014, [and] that’s on the list.”

Also on the manifesto was the 2015 mass shooting in San Bernardino, California, the 2015 terror attack in Paris, France, and the 2016 assault on a gay nightclub in Orlando, Florida. All three of those stories, and many others on the list, dominated the news cycle for weeks. The Orlando incident even made news a few weeks ago after the widow of the attacker, Omar Mateen, was arrested over allegations of obstruction of justice, among other charges.
